Radio-frequency assembly with impedance matching filter

A radio-frequency assembly (“RF assembly”) comprising:

• a signal source having a semiconductor amplifier output;
• at least one impedance matching filter with a first interface and a second interface;
• and
• a radio-frequency waveguide (“RF waveguide”);
• wherein the first interface is communicatively coupled to the signal source for transmitting an RF signal from the signal source to the at least one impedance matching filter;
• wherein the second interface is communicatively coupled to the RF waveguide for transmitting the RF signal from the at least one impedance matching filter to the RF waveguide;
• wherein a first impedance value at the first interface corresponds to an impedance value at the semiconductor amplifier output;
• wherein a second impedance value at the second interface corresponds to an impedance value at the RF waveguide;
• and
• wherein the first impedance value and the second impedance value have different values.
